OpenArm open-sources a humanoid, CAD to teleop
Lukas Ziegler profiled the Tokyo project, which sells as a kit or prebuilt and shows no task demos.
Lukas Ziegler profiled OpenArm, an open-source humanoid robot from @enactic_ai in Tokyo that ships with the whole stack. Full CAD, control code, firmware and simulation tools, which is to say everything needed to build, modify and operate it.
The arms are designed to be compliant and backdrivable. Teleoperation is supported, with force feedback and real-time gravity compensation so operators can guide the arm naturally.
It comes with full CAD, control code, firmware, and simulation tools, everything needed to build, modify, and operate it.
The arms are compliant and backdrivable, meaning you can push them by hand and they give instead of fighting you. Teleoperation (a human controlling the robot remotely) is supported with force feedback and real-time gravity compensation, so an operator can guide the arm without wrestling its own weight.
Simulation first
On the software side, OpenArm works with MuJoCo and Isaac Sim, two physics simulators, so developers can test policies in a virtual environment before running them on the real hardware. That pairing, simulation support plus teleop with force feedback, is the part that matters most for a lab. It is the standard loop for collecting demonstrations and training policies, and here you own every layer of the machine doing it.
You can assemble it yourself from a kit or buy it prebuilt. Ziegler says the goal is accessibility for research labs, small teams and enthusiasts, and that the project aims to lower the barrier for experimenting with dexterous manipulation.
Shown versus claimed
This is a hardware and tooling release, not a capability claim. The post shows no tasks, no success rates and no price. Nobody is saying OpenArm folds laundry or tends a machine, and nothing in the source suggests otherwise. What is on offer is a documented, modifiable platform, and the value of that depends entirely on what people build with it.
That is still a meaningful gap to fill. Most of the humanoid news cycle is closed hardware with a polished video attached, where outside researchers cannot check the claim or reuse the platform. An open humanoid with published CAD and firmware is the opposite bet. The interesting numbers, if they come, will come from the people who buy the kit rather than from the people who shipped it.
